'llhisinvention relates to a follow rest for lathes and in particular to a Work supporting .rest adapted to be mounted on and moved` with the tool support andy adapted to l bear against the Worlrat a point opposite the point of ei-igagement of the. tool.

it; principal obj ect of the present invention is to provide a Jtollovv rest 'for lathes that may .be ,mounted directly upon and be longitudinally adjustable relative to the tool rest.`

another object et the invention is to pro? vide` a simple, inexpensive form of follou7 rest adapted to be readily adjustable for differentpositions of the tool and having a pair of rollers in engagement with theworlc at spaced apart points, one of which rollersl is positioned directly opposite `the point of contact of thetool.

Another object o'll the invention is to pro- `vide a follow rest ada ated to engagea dove.

. y b E tail; Way provided on a supporting member fastened to the upper surface ot lthe tool rest so that it may be moved with and in adirectionA yparallel to the movement of `the tool, and also to provide a member transversely adjustable in said member vfor ad'- justing the roller ot the i'ollorvY rest tor dit ferent diameters of work.

, li stillI further object ot thev inventionis to provide a pivotal mounting onthe follow rest. for; one of the nforlr` engaging members n or` rollers that it may be adjusted onthe transversely adjustable member for different diameters oit Work, thus formingA a supplementary support for the Work. i

1With these and other Objects in view,` our invention consists in the features ot construction and operation set forth in the following specification andi illustrated in the accompanying drawing:

In the accompanying drawing annexed hereto and forming a part of this specification, we have shown our invention embodied in a work rest for a medium size lathe but it will be understood that the invention can be otherwise embodiedkand that the drawing is not to be construed as defining or limiting the scope "of the invention, the claims appended to this specification being relied upon for that purpose.

In the drawing:y l* igure l is a transverse sectional View of` the complete follow rest taken on line l-l oil-Fig.

Fig. 2 is a Vplan View of the completefol-l loivrest, and

l i l i tig. 3 is a sectional view taken substantially on linel 3-3 of Figui.

i In the above mentioned drawing, We have shown but one embodiment of the invention which is new deemed `preferable but itis to be understood that changes and modilica.- j

of the tool support andextending in a direction parallel to the `movement of the tool during its operation; second, a body member adapted to be mounted on and adjustably secured tosaid Ways in any. longitudinal position; third, a bar extending transversely through the bodv member andV hav-r ing ay vrorlr engaging roller depending from one end; fourth, adjusting means br the bar; fiftlua suppleniiental `roller mounted on a freely swinging arm in the bar; ,andI sixth, means to retain the supplementary roller se-f' cureljT in any adjusted position. Y

Referring more .indetail to the ligures Ot the drawing, We show a portion ot' a tool cross-slide l() ot anv engine lathe On which may be mounted a tool holder ll ot special form. This tool holder ll, as shown, is pro-` vid-ed With a central bolt`-12by means of which it may be rigidly secured tothe tool cross-slide 10. One or more tools 13 may be providedA YandA adjustably secured in the holder `ll in thevmanner clearly shownin thefigures. The tool holder is provided With two short vertical projections 14 at opposite sides, the space between them being ample for placing the cutting tools 13 of any desired form. TWO of such tools 13 are shown, the space betweeirtliem being lilled with suitable spacers.

Just above the tools 13 is provided a dovetailed member l5 preferably secured to the tool holder ll by screws 16 extending into the projections 14. This member 15 extends in a direction parallel to the direction of movement of the tool 13 during the cutting operation. The tools 13 are secured in position in theirholder 11 by screws 17 through this member 15, two of which are shown for each tool. Also a screw 18 may be provided passing through one of the projections 14 to hold the tools 13 vfrom lateral displacement. Adjusting screws 19 in rear ofthe tools 13 for forcing them forward and for holding them rigidly in adjusted position may also be provided if desired.

Mounted on this member 15 and engaging dove-tailed ways thereon is a body member 20 provided with a clamping screw 21 so that it may be securely clamped in any desired and adjustable position along the member 15. Extending transversely through the body member 20 is a bar 22 having a depending head portion 23 at its inner end. By means of a screw 24 entering one end of this bar 22 and engaging a. nut 25 at the forward end of the screw 24, the position of the bar 22 may be adjusted transversely.I To prevent rotative movement of the bar 22, which may be of circular section, a screw 26 is mounted in the body member 20 and contacts with the bar 22 on a flattened portion.

Mounted in the head portion 23 of the bar 22 and at its lower end is a small, freely rotatable work engaging roller 27. It will be seen from this construction that the bar 22 may be adjusted transversely relative to the tool 13 so that the small roller 27 may engage a portion of the work lV being turned. Also this roller 27 maybe adjusted for any diameter of work W or position relative to that of the tool 13.

Also mounted on thehead portion 23 of the bar 22 is a freely swinging arm 28 pivoted as shown in Fig. 2 and having a small roller 29 at its lower or free end. This roller 29 is adapted to engage a. portion of the work l/V being turned spaced from the point of engagement of the first` roller 27. The positions of this arm 28 and roller 29 are clearly shown in Fig. 2 for work of relatively large diameter. By means of an adjusting screw 30, the position of this roller 29 may be varied and it may be forced to any adjusted position against the work lV. To hold this supplementary roller 29 in adjusted position, clamping screws 31 and 32 are provided. One of these screws 31 bears against the pivot carrying the arm 28 and the other screw 32 forces al bearing member against the adjusting screw 30.

lVhat we claim is:

1. A follow rest for lathes comprising in combination, a tool support, a supporting member thereon, a body member adapted to be mounted on the supporting member and movable with the tool support of the lathe, means on said supporting member to adjust the position of the member longitudinally of the tool support, a bar movable transversely in said member upon a fixed axis, a work engaging roller rotatably mounted in fixed position on the inner end of said bar, and means to hold said bar with the roller in any adjusted position.

2. A follow rest for lathes comprising in combination, a tool support, a supporting member thereon, a body member adapted to be mounted on the supporting member and movable above the tool support of the lathe, means above said tool support to adjust said body member in the direction of movement of said tool support, a bar movably mounted in said member, a work engaging roller depending from said bar, and means to hold said bar with the roller in any adjusted position.

3. A follow rest for lathes comprising in combination, a body member adapted to be mounted on and movable with the tool support of the lathe, a bar movably mounted in said member, a work engaging roller on said bar, a supplementary roller pivotally mounted on said bar, means to hold said bar with the first roller in any adjusted position, and means to hold the supplementary roller in any adjusted position relative to said first roller.

4. A follow rest for lathes comprising in combination, a body member adapted to be mounted on and movable with the tool support of the lathe, a bar movably mounted in said member, a work engaging roller on said bar, a pivotally mounted arm adjustable on said bar, means to hold said bar with the first roller in any adjusted position, and means to secure the pivotal arm in any desired position.

In testimony whereof, we hereto affix our signatures.
